Short answer: the JBL Stage 250B. It ranks #52 of 88 bookshelf speakers by sound quality, rated 3.2/5, at $439.95; the ELAC BS U5 ranks #58, rated 2.9/5, and costs $856, which makes this an easy call rather than a real tradeoff.
Why pick the JBL Stage 250B: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The catch: Its objective score is good rather than class-leading, and the rear port needs some wall clearance.
Why pick the ELAC BS U5: This slim three-way coaxial design (an Andrew Jones creation) shows a fairly even on-axis response up to 3kHz, with off-axis behavior notably smoother than the on-axis curve. The tradeoff: Distortion is very high right at both crossover points - around 270Hz (mid-range) and 2700Hz (tweeter) - at both 86dB and 96dB SPL/1m, exceeding 3% at the mid-range crossover.
Worth knowing: the ELAC BS U5 has been discontinued and is hard to find new at this point.
Buy the JBL Stage 250B. It is rated higher for sound quality than the ELAC BS U5 and costs less, so only choose the other one for a particular feature it does better.

JBL Stage 250B: $439.95 per pair Amazon JBL eBay
Older model: the JBL Stage A130 (ranked lower, rated 2.1/5).
Pros: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The current Stage 2 model offers solid build details, magnetic grilles and useful 56Hz measured extension at an accessible price. Measured bass extension of 64.5Hz (-3dB).
Cons: Its objective score is good rather than class-leading, and the rear port needs some wall clearance. At 86dB sensitivity and six-ohm nominal impedance it is not especially easy to drive, while the compact woofer limits deep-bass output.

ELAC BS U5: $856 per pair Discontinued eBay
Pros: This slim three-way coaxial design (an Andrew Jones creation) shows a fairly even on-axis response up to 3kHz, with off-axis behavior notably smoother than the on-axis curve. Predicted in-room response looks like it should give good tonality. Vertical directivity is better than average, a benefit of the coaxial layout. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Distortion is very high right at both crossover points - around 270Hz (mid-range) and 2700Hz (tweeter) - at both 86dB and 96dB SPL/1m, exceeding 3% at the mid-range crossover. Minimum impedance dips to 3.4 ohms with a possible resonance around 500Hz visible in the impedance/phase curve. Discontinued.
